Understanding the Blockchain Structure

Blockchain technology serves as the foundation for most cryptocurrencies. It ensures the integrity and transparency of all transactions. Here's an overview of the process:

  1. Transaction Initiation: A user creates a transaction and broadcasts it to the network.
  2. Validation: Miners or validators confirm the legitimacy of the transaction.
  3. Block Creation: The transaction is added to a block, which is then linked to the previous block.
  4. Finalization: Once added to the blockchain, the transaction is permanent and irreversible.
